The National Flag is a horizontal tricolor of deep saffron (Kesari) at the top, white in the middle and dark green at the bottom. The ratio of the width of the flag to its length is two to three. In the center of the white band is a wheel, in navy blue, which represents the Charkha. Its design is that of the wheel (Chakra) which appears on the abacus of the Sarnath Lion Capital of Ashoka. Its diameter approximates to the width of the white band and it has 24 spokes. The design of the National Flag was adopted by the Constituent Assembly of India on the 22nd July 1947. Its use and display was regulated by code.
